Chronic administration of aprindine during maintenance hemodialysis.
Aprindine was administered for 12 months to 8 hemodialysis patients suffering from arrhythmias. The serum aprindine concentration ranged from 0.3 to 0.6 microgram/ml, and did not increase with time during the 1-year treatment period. The PQ interval was temporarily prolonged in the first and second months, but the QRS and QT intervals were not changed by chronic aprindine treatment. The changes of the PQ interval in the second month of treatment were directly correlated with the serum aprindine concentration. No alterations of the ECG findings were observed when aprindine was discontinued. The cardiothoracic ratio (chest radiography) and laboratory findings were also not influenced by either aprindine treatment or its withdrawal. In conclusion, aprindine may be safely administered for at least 1 year to arrhythmia patients on maintenance hemodialysis.
